RESONANCE AND NONRESONANCE FOR P-LAPLACIAN PROBLEMS WITH WEIGHTED EIGENVALUES CONDITIONS
(Amer Inst Mathematical SciencesSpringfieldEUA, 2009)
The spectrum of the p-Laplacian with singular weight

Eigenvalue homogenisation problem with indefinite weights
(Australian Mathematics Publ Assoc Inc, 2016-02)
In this work we study the homogenisation problem for nonlinear elliptic equations involving p-Laplaciantype operators with sign-changing weights. We study the asymptotic behaviour of variational eigenvalues which consist ...
Multiple positive solutions for quasilinear problems with indefinite sublinear nonlinearity

MULTIPLICITY OF SOLUTIONS FOR GRADIENT SYSTEMS

Periodic solutions for indefinite singular equations with singularities in the spatial variable and non-monotone nonlinearity
(American Institute of Mathematical Sciences, 2018-10)
TWe prove the existence of T−periodic solutions for the second order non-linear equation u0 1 − u02 0 = h(t)g(u), where the non-linear term g has two singularities and the weight function h changes sign. We find a relation ...
Multiple solutions for a class of quasilinear problems

A lyapunov type inequality for indefinite weights and eigenvalue homogenization
(American Mathematical Society, 2016-04)
In this paper we prove a Lyapunov type inequality for quasilinear problems with indefinite weights. We show that the first eigenvalue is bounded below in terms of the integral of the weight, instead of the integral of its ...
A nodal inverse problem for second order Sturm-Liouville operators with indefinite weights
(Elsevier Science Inc, 2015-04)
In this paper we study an inverse problem for weighted second order Sturm-Liouville equations. We show that the zeros of any subsequence of eigenfunctions, or a dense set of nodes, are enough to determine the weight. We ...
